Sixteen
days after the London Marathon began, 32-year-old Claire Lomas completed
the race.

Before you think that's awfully slow, be assured that it's quite a remarkable
achievement: See, Claire is paralyzed form the chest down and wore a bionic
suit for the marathon race.

The £43,000 ReWalk suit she used for the marathon, designed
by Israeli entrepreneur Amit Goffer, enables people with lower-limb
paralysis to stand, walk and climb stairs through motion sensors and
an onboard computer system.

A shift in the wearer's balance, indicating their desire to take,
for example, a step forward, triggers the suit to mimic the response
that the joints would have if they were not paralysed.
